309 ways to do $A++ in Perl

Here is a list of 309 code examples how to increment variable in Perl.

I think that is it very funny, creative and awful at the same time.

As far as I can see, not all code examples are working and not every one is interesting, but some of the solutions are truly magical.

Here is one example created by Maddingue:


eval((map{s/^./\$/,s/ //g;$_}(split"$/",<<'')[-1])[0]);
    A A        +       +
   A   A       +       +
  AAAAAAA   +++++++ +++++++
 A       A     +       +
A         A    +       +;

print $A;
